In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0053] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0054] This application scheme introduces the structure of a wall-mounted air conditioner 10000.

[0055] Before this, let's first introduce the structure of a common air conditioner. A common air conditioner is a split-type air conditioner, which includes an indoor unit and an outdoor unit. The indoor unit and the outdoor unit are connected by a pipe to transmit refrigerant. The indoor unit includes an indoor heat exchanger 2 and a heat exchange fan 3.

[0056] The outdoor unit includes a compressor, an outdoor heat exchanger, an outdoor fan and a throttling device. The compressor, outdoor heat exchanger, throttling device and indoor heat exchanger 2 connected in sequence form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the outdoor heat exchanger and the indoor heat exchanger 2 respectively to realize the cooling mode or heating mode of the air conditioner.

[0057] The compressor is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0058] The outdoor heat exchanger is configured to exchange heat between outdoor air and the refrigerant transported through the outdoor heat exchanger. For example, in the air conditioner's cooling mode, the outdoor heat exchanger operates as a condenser, causing the refrigerant compressed by the compressor to condense by dissipating heat to the outdoor air through the outdoor heat exchanger. In the air conditioner's heating mode, the outdoor heat exchanger operates as an evaporator, causing the decompressed refrigerant to absorb heat from the outdoor air through the outdoor heat exchanger and evaporate.

[0059] In some embodiments, the outdoor heat exchanger further includes heat exchange fins to expand the contact area between the outdoor air and the refrigerant transmitted in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0060] The outdoor fan is configured to draw outside air into the outdoor unit and send the outside air after heat exchange with the outdoor heat exchanger to the outside. The outdoor fan provides power for the flow of the outdoor air.

[0061] A throttle element is connected between the outdoor heat exchanger and the indoor heat exchanger 2. It regulates the pressure of the refrigerant flowing through the outdoor heat exchanger and the indoor heat exchanger 2, thereby adjusting the refrigerant flow rate between the outdoor heat exchanger and the indoor heat exchanger 2. The flow rate and pressure of the refrigerant flowing between the outdoor heat exchanger and the indoor heat exchanger 2 will affect the heat exchange performance of the outdoor heat exchanger and the indoor heat exchanger 2. The throttle element can be a throttle tube, an electronic valve, or the like. If the throttle element is an electronic valve, the throttle opening is adjustable to adjust the flow rate and pressure of the refrigerant flowing through the throttle element.

[0062] In some solutions, the air conditioner further includes a four-way valve, which is connected to the refrigerant circuit and configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner performs cooling mode or heating mode.

[0063] The indoor heat exchanger 2 is configured to perform heat exchange between the indoor air and the refrigerant transmitted in the indoor heat exchanger 2. In some embodiments, the indoor heat exchanger 2 further includes heat exchange fins to expand the contact area between the indoor air and the refrigerant transmitted in the indoor heat exchanger 2, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0064] The heat exchange fan 3 is configured to draw indoor air into the indoor unit and deliver the indoor air after heat exchange with the indoor heat exchanger 2 to the room. The heat exchange fan 3 provides power for the flow of indoor air.

[0065] The air conditioner also includes a control device, which is primarily used to control the operating frequency of the compressor and the opening of the throttle element. Some control devices can also control the speed of the outdoor fan and the speed of the heat exchange fan 3. The control device is connected to the compressor, throttle element, outdoor fan, and heat exchange fan 3 via data cables to transmit communication information.

[0066] The control device includes a processor, which may include a central processing unit (CPU), a microprocessor (microprocessor), or an application specific integrated circuit (ASIC), and may be configured to perform corresponding operations described in the control device when the processor executes a program stored in a non-temporary computer-readable medium coupled to the control device.

[0067] Non-transitory computer-readable storage media may include magnetic storage devices (e.g., hard disk, floppy disk, or tape), smart cards, or flash memory devices (e.g., erasable programmable read-only memory (EPROM), cards, sticks, or keyboard drives).

[0068] The wall-mounted air conditioner 10000 proposed in this application is an indoor unit. The wall-mounted air conditioner 10000 is usually installed on a wall, for example, can be installed in the upper area of ​​an indoor wall.

[0069] Please refer to the following Figures 1-15 A wall-mounted air conditioner 10000 according to an embodiment of the present application is described.

[0070] The wall-mounted air conditioner 10000 according to an embodiment of the present application includes a main body 1000 .

[0071] like Figure 1 and Figure 7 As shown, the main body 1000 includes a housing 1, an accommodating cavity V1 is formed inside the housing 1, and a heat exchange air inlet 11 is formed on the housing 1. The housing 1 can play a protective role and constitute the overall appearance structure of the wall-mounted air conditioner 10000.

[0072] Typically, the housing 1 is an elongated, horizontally oriented enclosure. This means the enclosure 1 is mounted horizontally on a wall. In some embodiments, the enclosure 1 is mounted horizontally on a wall to drain condensed water.

[0073] like Figure 2 and Figure 3 As shown, the main body 1000 further includes a heat exchange fan 3, which is located on the side of the indoor heat exchanger 2 away from the heat exchange air inlet 11. When the heat exchange fan 3 is in operation, it draws indoor air into the housing 1 through the heat exchange air inlet 11. After heat exchange with the indoor heat exchanger 2, the heat exchanged air is delivered to the room through the heat exchange air outlet 61.

[0074] In this application, the heat exchange fan 3 is located on the side of the indoor heat exchanger 2 away from the heat exchange air inlet 11. It can be understood that the heat exchange fan 3 is a power drive component that drives the indoor air to exchange heat with the indoor heat exchanger 2 by rotating, and is also a power drive component for air supply.

[0075] like Figure 2 and Figure 3 As shown, the wall-mounted air conditioner 10000 further includes: a fresh air fan 5 , which is a centrifugal fan with axial air intake and radial air discharge, and is located on a side of the heat exchange fan 3 away from the drive motor 4 .

[0076] By placing the heat exchange fan 3 on the side of the indoor heat exchanger 2 away from the heat exchange air inlet 11, the air force generated when the heat exchange fan 3 rotates can be evenly distributed. A part of it is distributed to the air inlet side, so that the inhaled air overcomes the wind resistance generated by the indoor heat exchanger 2 when flowing into the first volute air duct V2, and the other part is distributed to the air supply side, so that the heat-exchanged air can be transported over a longer distance when blown out from the heat exchange air outlet 61.

[0077] In some embodiments, the fresh air fan 5 and the heat exchange fan 3 are coaxially designed, and the driving motor 4 can drive the fresh air fan 5 and the heat exchange fan 3 to rotate synchronously when in working condition. The heat exchange fan 3 and the fresh air fan 5 are set to a coaxial structure, and a driving motor 4 can be used to drive the fresh air fan 5 and the heat exchange fan 3 to rotate synchronously, thereby reducing the number of motors and reducing costs. Compared with the solution of assembling the heat exchange fan 3 and the fresh air fan 5 separately, the number of assembly times can be reduced, the assembly error can be reduced, and the assembly difficulty can be reduced.

[0078] Centrifugal fans offer compact structure, high air volume, and low noise. Fan noise decreases significantly as the speed decreases, so a smaller centrifugal fan can be used for fresh air fan 5 to meet high air volume requirements. Centrifugal fans also produce low vibration noise and are less likely to resonate with the indoor heat exchanger 2, effectively controlling the overall vibration and noise of the wall-mounted air conditioner 10000.

[0079] like Figure 1 As shown, the main body 1000 also includes an indoor heat exchanger 2, which is disposed within the accommodating chamber V1. As described above, the indoor heat exchanger 2 is a link in the refrigerant circuit, through which refrigerant circulates, and is used to cool or heat the air flowing through the surface of the indoor heat exchanger 2. In a wall-mounted air conditioner 10000, the indoor heat exchanger 2 is typically arranged to extend along the length of the casing 1. For example, the indoor heat exchanger 2 may be a two-fold or three-fold heat exchanger, with each fold of the indoor heat exchanger 2 being a plate-like structure extending along the length.

[0080] like Figure 2 and Figure 3 As shown, the main body 1000 further includes a drive motor 4, which is disposed in the accommodating cavity V1. The drive motor 4 is used to drive the heat exchange fan 3 to rotate, so that the air inside the air conditioner exchanges heat with the indoor space.

[0081] In the present embodiment, the drive motor 4 is located at one end of the main body 1000 in the longitudinal direction. This facilitates installation and maintenance of the drive motor 4, and the main body 1000 as a whole does not need to be excessively tall or thick due to the placement of the drive motor 4. Here, the height direction of the main body 1000 is consistent with the vertical direction, the thickness direction of the main body 1000 is consistent with the front-to-back direction, and the length direction of the main body 1000 is consistent with the left-to-right direction.

[0082] The main body 1000 further includes a base 6 disposed in the accommodating cavity V1 . The base 6 is an installation support structure inside the main body 1000 , and the indoor heat exchanger 2 can be installed on the base 6 .

[0083] Among them, such as Figure 4 and Figure 6 As shown, the base 6 is used to form the first volute tongue air duct V2 and the second volute tongue air duct V3, and a heat exchange air outlet 61, a first fresh air inlet 62 and a first fresh air outlet 63 are formed on the base 6.

[0084] In this embodiment, at least a portion of the outline of the second volute tongue air duct V3 is formed by the base 6 , and at least a portion of the outline of the first volute tongue air duct V2 is formed by the base 6 .

[0085] The heat exchange fan 3 is arranged in the first volute-tongue air duct V2. After the indoor air enters the casing 1, the flow direction is guided by the first volute-tongue air duct V2 to ensure that the indoor air encounters less resistance when flowing through the indoor heat exchanger 2.

[0086] The fresh air fan 5 is arranged in the second volute-tongue air duct V3, and the outdoor air can enter the casing 1 through the first fresh air inlet 62 and then pass through the second volute-tongue air duct V3, and the outdoor air entering the second volute-tongue air duct V3 can enter the room from the fresh air outlet.

[0087] Among them, such as Figure 1 As shown, in the height direction of the main body 1000 , the heat exchange air inlet 11 is located above the heat exchange air outlet 61 .

[0088] like Figure 2 As shown, a heat exchange air outlet 61 is provided on the casing 1, and a heat exchange air outlet 61 is formed on the base 6. When the heat exchange fan 3 is running, the indoor air is sucked into the casing 1 from the heat exchange air inlet 11. After heat exchange with the indoor heat exchanger 2, the heat-exchanged air is sent to the room from the heat exchange air outlet 61.

[0089] In this way, the indoor ambient temperature can be regulated. The indoor heat exchanger 2 can be used as an evaporator to provide cooling airflow to the indoor space through the heat exchange outlet 61, or the indoor heat exchanger 2 can be used as a condenser to provide heating airflow to the indoor space through the heat exchange outlet 61.

[0090] In the present application, the heat exchange air inlet 11 is located above the heat exchange air outlet 61 in the height direction of the main body 1000, so that air can flow in from above and out from below. In the present application, the height direction of the main body 1000 is the up-down direction.

[0091] It is understood that the main body 1000 is usually mounted on a wall. To avoid interfering with people's daily lives, the main body 1000 is usually hung at a higher position. By setting the main body 1000 to blow out the heated air from below, the blown heated air is less likely to be blocked by the roof or the ground. In this way, the heated air encounters less resistance and consumption during the blowing process, and the air supply range is wide, so that the heated air can flow to the entire indoor space as quickly as possible, thereby improving the heat exchange efficiency.

[0092] The heat exchange air inlet 11 is located above the heat exchange air outlet 61. The heat exchange air inlet 11 can take in air from above, which can avoid taking in air from the heat exchange air outlet 61, and avoid the heat exchange air being directly sucked into the heat exchange air inlet 11 after being blown out from the heat exchange air outlet 61, thereby reducing the heat exchange air idling and not participating in the indoor heat exchange process.

[0093] In some embodiments, as Figure 1 As shown, the heat exchange air inlet 11 is located at the top of the housing 1, that is, in an area that is invisible to the user. Hiding the heat exchange air inlet 11 can improve the appearance.

[0094] In some embodiments, as Figure 4 As shown, the heat exchange air outlet 61 is located on the front side of the base 6 and close to the bottom, or it can be said that the heat exchange air outlet 61 is located at the front lower corner of the base 6. At this time, the heat exchange air blown out by the heat exchange air outlet 61 flows forward and downward at the same time, so that the heat exchange air can sink and fall on people or objects on the ground after being sent to a certain distance, so that people or objects on the ground can be in a comfortable indoor environment as soon as possible.

[0095] In some embodiments, the heat exchange air outlet 61 is located directly in front of the base 6, that is, the heat exchange air outlet 61 blows air toward the front side of the main body 1000. It is understood that the side of the main body 1000 connected to the wall is usually called the back or rear side, and the side opposite to the rear side is called the front side. Therefore, when the heat exchange air outlet 61 is located directly in front of the base 6, the air is discharged away from the wall, the blowing resistance is small, and the air supply range is wide.

[0096] In the related technology, the fresh air air conditioner includes a heat exchange fan and a fresh air fan. A heat exchange duct for installing the heat exchange fan is provided on the base. The fresh air volute is installed at one end of the base. The fresh air volute forms a fresh air duct for installing the fresh air fan. Since the heat exchange fan and the fresh air fan are integrated into one design, the heat exchange fan and the fresh air fan are different fan types and correspond to different air ducts. The fresh air volute and the base will produce assembly errors during the installation process. The coaxial heat exchange fan 3 and the fresh air fan will also produce assembly errors during the installation process with the corresponding air ducts. The fresh air air conditioner will produce noise and return air problems when working.

[0097] According to the wall-mounted air conditioner 10000 provided in the embodiment of the present application, the first volute tongue air duct V2 and the second volute tongue air duct V3 are integrated on the base 6, the heat exchange fan 3 is arranged in the first volute tongue air duct V2, and the fresh air fan 5 is arranged in the second volute tongue air duct V3, that is, the first volute tongue air duct V2 and the second volute tongue air duct V3 are an integrated structure, and the coaxially arranged heat exchange fan 3 and the fresh air fan 5 can be installed on the base 6 at the same time, which can avoid assembly errors in the assembly process of the first volute tongue air duct V2 and the second volute tongue air duct V3, and reduce position deviations in the assembly of dual air ducts and dual fans, thereby improving the relative position relationship between the air duct and the fan, thereby improving the noise and return air problems of the whole machine during operation in the first aspect, shortening the length of the common axis between the fresh air fan 5 and the heat exchange fan 3 in the second aspect, improving the stability of the coaxial fan, and shortening the lateral size of the whole machine in the third aspect, reducing the number of parts of the whole machine, improving assembly efficiency, and reducing costs.

[0098] like Figure 1 and Figure 2As shown, the present application also provides a wall-mounted air conditioner 10000, comprising: a main body 1000, the main body 1000 comprising: a casing 1, a base 6, an indoor heat exchanger 2, a heat exchange fan 3, a drive motor 4, a fresh air fan 5 and a fresh air volute; a accommodating chamber V1 is formed inside the casing 1, and a heat exchange air inlet 11 is formed on the casing 1; the base 6 is located in the accommodating chamber V1, and the base 6 is used to form a first volute tongue air duct V2; the indoor heat exchanger 2 is arranged in the accommodating chamber V1; the heat exchange fan 3 is located on the side of the indoor heat exchanger 2 away from the heat exchange air inlet 11, and is located in the first volute tongue air duct V2; the drive motor 4 is arranged in the accommodating chamber V1, and is located at one end in the length direction of the main body 1000, for driving the heat exchange fan 3 to rotate, so that the air inside the air conditioner is heat-exchanged with the indoor space; the fresh air fan 5 is a centrifugal fan with axial air intake and radial air outlet, and the fresh air fan 5 is located on the side of the heat exchange fan 3 away from the drive motor 4.

[0099] The fresh air volute includes: a fresh air seat 8 and a fresh air cover 7. The fresh air seat 8 is integrally formed on the base 6. The fresh air cover 7 is located above the fresh air seat 8. The fresh air cover 7 and the fresh air seat 8 together form a second volute tongue air duct V3 to accommodate the fresh air fan 5.

[0100] Among them, the fresh air seat 8 and the fresh air cover 7 form a fresh air module, and the fresh air module is used for ventilation.

[0101] The fresh air seat 8 and the base 6 are integrally formed. For example, the fresh air seat 8 and the base 6 can be integrally formed and connected by 3D printing, integral molding of composite materials or injection molding.

[0102] In this embodiment, the fresh air seat 8 and the base 6 are integrally formed, that is, the fresh air seat 8 and the base 6 are a single unit. Compared with the related art solution in which the fresh air seat 8 and the base 6 are separate structures and need to be connected by fasteners, this eliminates the steps of clamping or bolting the fresh air seat 8 and the base 6, simplifies the production process, and can reduce the assembly errors caused by the fresh air volute and the base 6 during the installation process.

[0103] According to the wall-mounted air conditioner 10000 of the present application, the fresh air seat 8 and the base 6 are integrally formed, the heat exchange fan 3 is arranged in the first volute tongue air duct V2, and the fresh air fan 5 is arranged in the second volute tongue air duct V3, that is, the first volute tongue air duct V2 and the second volute tongue air duct V3 are an integrated structure, and the coaxially arranged heat exchange fan 3 and the fresh air fan 5 can be installed on the base 6 at the same time, which can avoid assembly errors in the assembly process of the first volute tongue air duct V2 and the second volute tongue air duct V3, and reduce the position deviation in the assembly of dual air ducts and dual fans, thereby improving the relative position relationship between the air duct and the fan, thereby improving the noise and return air problems of the whole machine during operation on the first aspect, shortening the length of the common axis between the fresh air fan 5 and the heat exchange fan 3 on the second aspect, improving the stability of the coaxial fan, and shortening the lateral size of the whole machine on the third aspect, reducing the number of parts of the whole machine, improving assembly efficiency, and reducing costs.

[0104] In some embodiments, as Figure 4 As shown, the first fresh air outlet 63 and the heat exchange outlet 61 are arranged on the same side of the base 6.

[0105] Exemplarily, the heat exchange air outlet 61 is provided at the bottom of the base 6 to guide the heat exchanged air to flow downward into the room. Similarly, the fresh air first air outlet 63 is also provided at the bottom of the base 6 to guide the fresh air to flow downward into the room.

[0106] Exemplarily, the heat exchange outlet 61 is provided below the base 6 to guide the heat exchanged air to flow forward and downward into the room. Similarly, the fresh air first outlet 63 is also provided below the base 6 to guide the fresh air to flow forward and downward into the room.

[0107] In this embodiment, the first fresh air outlet 63 and the heat exchange outlet 61 are arranged on the same side of the base 6, which can improve the working direction of the fresh air fan 5 and the heat exchange fan 3, improve the coaxial stability of the fresh air fan 5 and the heat exchange fan 3, and make the fresh air outlet area and the outlet area of ​​the heat exchange outlet 61 close to or even partially overlap, which is conducive to the mixing of fresh air and the indoor air after heat exchange. On the one hand, it improves the uniformity of the fresh air after mixing in the indoor air. On the other hand, the fresh air can absorb the cold or heat of the indoor air after heat exchange, so that the temperature of the fresh air tends to the indoor temperature, thereby improving the blowing comfort.

[0108] In some embodiments, as Figure 10 As shown, in the height direction of the main body 1000, the volute tongue 64 of the first volute tongue air duct V2 is located above the heat exchange air outlet 61, thereby improving the vortex problem of the first volute tongue air duct V2.

[0109] In some embodiments, as Figure 11As shown, in the height direction of the main body 1000, the volute tongue 65 of the second volute tongue air duct V3 is located above the first fresh air outlet 63, thereby improving the vortex problem of the second volute tongue air duct V3.

[0110] In some embodiments, in the height direction of the main body 1000, the volute tongue 64 of the first volute tongue air duct V2 is located above the heat exchange air outlet 61, and the volute tongue 65 of the second volute tongue air duct V3 is located above the first fresh air outlet 63.

[0111] In this embodiment, by setting the position of the volute tongue 64 of the first volute tongue air duct V2 and the volute tongue 65 of the second volute tongue air duct V3, the stability of the coaxial dual fans can be improved, thereby improving the working direction of the dual fans, and improving the abnormal noise caused by the first volute tongue air duct V2 and the first volute tongue air duct V3 and the vortex and return air problems of the air conditioner.

[0112] In some embodiments, as Figure 3 and Figure 4 As shown, a second fresh air inlet 66 is formed on the base 6, and the base 6 is also used to form a fresh air cavity V4, which is located on a side of the second volute-tongue air duct V3 away from the first volute-tongue air duct V2.

[0113] At least part of the outline of the fresh air cavity V4 is formed by the base 6. A fresh air second air inlet 66 is provided between the fresh air cavity V4 and the second volute tongue air duct V3 to connect the fresh air cavity V4 with the second volute tongue air duct V3.

[0114] The fresh air flows from the first fresh air inlet 62 into the fresh air cavity V4 for storage, then flows from the fresh air cavity V4 through the second fresh air inlet 66 into the second fresh air inlet 66 , and then is discharged into the room from the first fresh air outlet 63 .

[0115] In this embodiment, the first fresh air inlet 62 is connected to the fresh air cavity V4, forming a fresh air cavity V4 at the air inlet end of the fresh air fan 5. The fresh air cavity V4 formed in this way can cover the axial air inlet end of the fresh air fan 5. The fresh air cavity V4 can be used to accommodate air, so that the air can enter the fresh air fan 5 vertically from the fresh air cavity V4 along the axial direction from the second fresh air inlet 66, thereby improving the suction efficiency of the fresh air fan 5 and reducing the suction loss.

[0116] Among them, the first fresh air inlet 62 and the heat exchange air outlet 61 are arranged on both sides of the first fresh air outlet 63, that is, the first fresh air inlet 62 and the heat exchange air outlet 61 are separated by the first fresh air outlet 63, and the first fresh air inlet 62 and the heat exchange air outlet 61 are separated by a certain distance. The heat exchange air will not be sucked into the first fresh air inlet 62, reducing the proportion of the heat exchange air intake at the first fresh air inlet 62, so that the total air outlet of the wall-mounted air conditioner 10000 is larger, thereby improving the overall circulation efficiency of indoor and outdoor air.

[0117] In some embodiments, as Figure 1 and Figure 3 As shown, the wall-mounted air conditioner 10000 further includes: a fresh air cover 7 , which is installed on the base 6 , and a second volute-tongue air duct V3 is formed between the fresh air cover 7 and the base 6 .

[0118] The fresh air cover 7 is detachably connected to the base 6. Exemplarily, the fresh air cover 7 and the base 6 can be connected by one or more methods such as plug-in connection, plug-in connection, and threaded connection.

[0119] Part of the outline of the second volute tongue air duct V3 is formed by the fresh air cover 7, and part of the outline of the second volute tongue air duct V3 is formed by the second volute tongue air duct V3.

[0120] A second fresh air outlet 71 is formed on the fresh air cover 7 , and the second fresh air outlet 71 is connected to the second volute-tongue air duct V3 .

[0121] The first fresh air outlet 63 and the second fresh air outlet 71 are respectively connected to the second snail-tongue air duct V3, and the first fresh air outlet 63 and the second fresh air outlet 71 are spaced apart along the height direction of the main body 1000, so that one of the first fresh air outlet 63 or the second fresh air outlet 71 can be selected to discharge fresh air according to the usage scenario, thereby selecting different fresh air outlet directions to improve the user experience.

[0122] For example, in the height direction of the main body 1000, the second fresh air outlet 71 is located above the main body 1000 to guide the fresh air to flow forward and upward into the room, reduce the fresh air blowing directly onto the human body, and increase the user experience; the first fresh air outlet 63 is located below the main body 1000 to guide the fresh air to flow forward and downward into the room, and improve the blowing comfort.

[0123] In some embodiments, the wall-mounted air conditioner 10000 further includes: a drain pipe, which leads to the outdoors.

[0124] Among them, a refrigerant pipe and a drain pipe are usually provided at one end of the main body 1000 in the length direction. The refrigerant pipe is used to connect the indoor heat exchanger 2 with the outdoor compressor and outdoor heat exchanger, and the drain pipe is used to discharge the condensed water generated in the wall-mounted air conditioner 10000.

[0125] A pipe escape opening is provided on the side wall of the housing 1, and the fresh air intake pipe and exhaust air outlet pipe are then horizontally arranged and then led out, facilitating the juxtaposition of at least one of the fresh air intake pipe and exhaust air outlet pipe with the drain pipe and refrigerant pipe. This juxtaposed multi-pipe arrangement is then wrapped with an external bundle of pipes or tie bands, resulting in the appearance of a single pipe. This reduces the number of connected pipes after the wall-mounted air conditioner 10000 is installed, resulting in a simpler appearance, facilitating assembly while also preventing the risk of multiple pipes colliding.

[0126] Among them, the base 6 is formed with a heat exchange drainage structure and a fresh air drainage structure. The heat exchange drainage structure is arranged on the air duct wall of the first volute tongue air duct V2, and the fresh air drainage structure is arranged on the air duct wall of the second volute tongue air duct V3. The fresh air drainage structure is connected to the heat exchange drainage structure, and the heat exchange drainage structure is connected to the drainage pipe, so that the condensed water in the second volute tongue air duct V3 flows into the heat exchange drainage structure and is discharged through the drainage pipe.

[0127] The temperature difference between the outdoor and indoor air introduced by the fresh air can easily cause condensation on the surface of the fresh air cover 7 and the second volute tongue air duct V3. The fresh air drainage structure is used to receive the condensation generated during the fresh air input, and the heat exchange drainage structure is used to receive the condensation generated during the heat exchange of the indoor air.

[0128] The heat exchange drainage structure is arranged on the side of the heat exchange fan 3 along the front-to-back direction, and the fresh air drainage structure is arranged on the side of the fresh air fan 5 along the front-to-back direction.

[0129] Among them, the fresh air drainage structure and the heat exchange drainage structure can be drainage troughs, and one end of the fresh air drainage structure is connected to the heat exchange drainage structure so that the condensed water in the fresh air drainage structure flows into the heat exchange drainage structure.

[0130] In the related art, sponge is pasted on the outer surface of the fresh air module to improve the situation of condensation water on the surface of the fresh air module, but this solution is inefficient and costly.

[0131] According to the wall-mounted air conditioner provided in the embodiment of the present application, a fresh air drainage structure is provided in the fresh air area of ​​the base 6, and the fresh air drainage structure is connected to the heat exchange drainage structure. The condensed water generated in the fresh air area flows into the heat exchange drainage structure through the fresh air drainage structure and is discharged. The sponge in the fresh air area can be eliminated, the production efficiency can be improved, and the condensation drainage problem in the fresh air area can be improved.

[0132] In some embodiments, as Figure 2 and Figure 5 As shown, the heat exchange drainage structure includes: a first heat exchange drainage structure 671 , a second heat exchange drainage structure 672 and a third heat exchange drainage structure 673 .

[0133] The first heat exchange drainage structure 671 is located at the front side of the base 6 , and is used to receive condensed water condensed on the front side of the casing 1 .

[0138] The first fresh air drainage structure 681 is located on the front side of the base 6 , and is used to receive condensed water on the front side of the fresh air cover 7 .

[0139] The end of the first fresh air drainage structure 681 facing the first volute air duct V2 is connected to the first heat exchange drainage structure 671 so that the condensed water in the first fresh air drainage structure 681 is discharged into the first heat exchange drainage structure 671 .

[0140] Illustratively, the end of the fresh air first drainage structure 681 facing the first volute air duct V2 can be connected to the heat exchange first drainage structure 671 to allow condensed water to flow into the heat exchange first drainage structure 671; or, a guide member is provided between the fresh air first drainage structure 681 and the heat exchange first drainage structure 671, and the guide member can be a water pipe, a water trough or other structure, and the condensed water flows into the heat exchange first drainage structure 671 through the guide member.

[0144] The end of the third fresh air drainage structure 683 facing the first volute tongue air duct V2 is connected to the second heat exchange drainage structure 672 so that the condensed water in the third fresh air drainage structure 683 is discharged into the second heat exchange drainage structure 672 .

[0145] Illustratively, the end of the third fresh air drainage structure 683 facing the first volute air duct V2 can be connected to the second heat exchange drainage structure 672 to allow condensed water to flow into the second heat exchange drainage structure 672; or, a guide member is provided between the third fresh air drainage structure 683 and the second heat exchange drainage structure 672, and the guide member can be a water pipe, a water trough or other structure, and the condensed water flows into the second heat exchange drainage structure 672 through the guide member.

[0146] Illustratively, the second fresh air drainage structure 682 and the third fresh air drainage structure 683 may be connected via a conducting structure, and the conducting structure may be a through hole, a through groove, or the like.

[0147] In some embodiments, as Figure 3 As shown, the base 6 is also used to form a fresh air cavity V4, which is located on the side of the second volute tongue air duct V3 away from the first volute tongue air duct V2. The fresh air cavity V4 is connected to the second volute tongue air duct V3, and the second volute tongue air duct V3 is used to install the fresh air fan 5.

[0148] Part of the outline of the fresh air cavity V4 is formed by the base 6 , and part of the outline of the fresh air cavity V4 is formed by the fresh air cover 7 .

[0149] After such arrangement, a fresh air cavity V4 is formed at the air inlet end of the fresh air fan 5. The fresh air cavity V4 formed in this way can cover the axial air inlet end of the fresh air fan 5. The fresh air cavity V4 can be used to accommodate air, so that the air can enter the fresh air fan 5 vertically along the axial direction from the fresh air cavity V4, thereby improving the suction efficiency of the fresh air fan 5 and reducing the suction loss.

[0150] like Figure 9 As shown, the second fresh air drainage structure 682 includes: a first drainage part 6821 and a second drainage part 6822.

[0151] The first drain 6821 is located at the rear of the second volute-tongue air duct V3. It collects condensed water from the area behind the fresh air cover 7 and corresponding to the second volute-tongue air duct V3. The first drain 6821 is connected to the third fresh air drainage structure 683, allowing condensed water within the first drain 6821 to drain into the third fresh air drainage structure 683.

[0152] like Figure 9 As shown, in some embodiments, the first drainage portion 6821 is provided with a first water guide hole 68211 connected to the third fresh air drainage structure 683 , and the condensed water in the first drainage portion 6821 is discharged into the third fresh air drainage structure 683 through the first water guide hole 68211 .

[0153] The second drainage portion 6822 is provided at the rear side of the fresh air cavity V4, and is used for receiving condensed water in the rear side of the fresh air cover 7 and in the area corresponding to the fresh air cavity V4.

[0154] In some embodiments, the second drainage portion 6822 can be connected to the fresh air third drainage structure 683 through the first drainage portion 6821, wherein the second drainage portion 6822 is connected to the first drainage portion 6821 to discharge the condensed water in the second drainage portion 6822 into the first drainage portion 6821.

[0155] Exemplarily, the end of the second drain portion 6822 facing the first drain portion 6821 is higher than the first drain portion 6821 along the height direction of the main body, so that the second drain portion 6822 and the first drain portion 6821 are connected, and the connection allows the condensed water in the second drain portion 6822 to be discharged into the first drain portion 6821.

[0156] Illustratively, a guide member is provided between the second drainage portion 6822 and the first drainage portion 6821 . The guide member may be a water pipe, a water tank or other structure, and the condensed water flows into the first drainage portion 6821 through the guide member.

[0157] In some embodiments, the second drainage portion 6822 is connected to the third fresh air drainage structure 683.

[0158] Illustratively, the second drainage portion 6822 is provided with a second water guide hole 68221 connected to the third fresh air drainage structure 683 , and the condensed water in the second drainage portion 6822 is discharged into the third fresh air drainage structure 683 through the second water guide hole 68221 .

[0159] In some embodiments, as Figure 12 As shown, along the height direction of the main body 1000, the fresh air first drainage structure 681 is higher than the heat exchange first drainage structure 671, so that the condensed water in the fresh air first drainage structure 681 can be discharged into the heat exchange first drainage structure 671 along the direction of gravity, reducing the storage amount of condensed water in the fresh air first drainage structure 681.

[0160] In some embodiments, as Figure 13 As shown, along the height direction of the main body 1000, the third drainage structure 683 for fresh air is higher than the second drainage structure 672 for heat exchange, so that the condensed water in the third drainage structure 683 for fresh air can be discharged into the second drainage structure 672 for heat exchange along the direction of gravity, thereby reducing the storage amount of condensed water in the third drainage structure 683 for fresh air.

[0161] In some embodiments, along the height direction of the main body 1000, the first fresh air drainage structure 681 is higher than the first heat exchange drainage structure 671, and the third fresh air drainage structure 683 is higher than the second heat exchange drainage structure 672, so that the condensed water in the first fresh air drainage structure 681 is discharged into the first heat exchange drainage structure 671 along the direction of gravity, and the condensed water in the third fresh air drainage structure 683 is discharged into the second heat exchange drainage structure 672 along the direction of gravity, thereby reducing the storage amount of condensed water in the first fresh air drainage structure 681 and the third fresh air drainage structure 683.

[0162] In some embodiments, as Figure 5 and Figure 7 As shown, from the direction away from to the direction close to the second heat exchange drainage structure 672 , the third fresh air drainage structure 683 is inclined downward along the height direction of the main body 1000 .

[0163] Among them, along the height direction of the main body 1000, the end of the third fresh air drainage structure 683 away from the second heat exchange drainage structure 672 is higher than the end of the third fresh air drainage structure 683 close to the second heat exchange drainage structure 672.

[0164] In this embodiment, the condensed water in the third fresh air drainage structure 683 is discharged into the second heat exchange drainage structure 672 along the direction of gravity, further reducing the storage amount of condensed water in the third fresh air drainage structure 683 and reducing the risk of condensed water in the heat exchange drainage structure flowing back into the fresh air drainage structure and overflowing.

[0165] In some embodiments, the wall-mounted air conditioner 10000 further includes: a fresh air cover 7, the fresh air cover 7 includes: a volute top wall 72 and a volute side wall 73, the volute top wall 72, the volute side wall 73 and the base 6 together form a second volute tongue air duct V3, the volute side wall 73 protrudes from the volute top wall 72 to form a water guide rib, see Figure 14 .

[0166] In this embodiment, by providing water-guiding ribs, the condensed water on the front side of the volute top wall 72 can be introduced into the first fresh air drainage structure 681, and the condensed water on the rear side of the volute top wall 72 can be introduced into the first drainage portion 6821. The condensed water on the volute top wall 72 and the condensed water on the volute side wall 73 can be separated to enter different fresh air drainage structures, thereby dispersing the condensed water condensed on the fresh air cover 7, reducing the amount of water in the fresh air drainage structure, and reducing the situation where the fresh air condensed water is sucked into the suction force of the fresh air operation.

[0167] In some embodiments, as Figure 15 As shown, the volute top wall 72 includes a front top wall 721 and a rear top wall 722 arranged along the front-to-back direction, and the volute side wall 73 includes a first side wall 731 and a second side wall 732 arranged along the length direction.

[0168] like Figure 8 As shown, the second side wall 732 and the first side wall 731 are arranged on both sides of the volute top wall 72 along the length direction to introduce the condensed water on the front side of the volute top wall 72 into the first fresh air drainage structure 681, and to introduce the condensed water on the rear side of the volute top wall 72 into the first drainage part 6821.

[0169] The length direction is the horizontal direction or the left-right direction of the main body 1000 .

[0170] Among them, the edges of the first side wall 731 protrude from the edges of the front top wall and the edges of the rear top wall, and the edges of the second side wall 732 are higher than the edges of the rear top wall, so as to guide the condensed water on the rear top wall into the first drainage part 6821, and guide the condensed water on the front top wall into the fresh air first drainage structure 681.

[0171] In some embodiments, as Figure 14 As shown, the first side wall 731 has a first water retaining rib 7311 , which protrudes from the first side wall 731 along the length direction to guide the condensed water on the first side wall 731 into the first heat exchange drainage structure 671 and the second fresh air drainage structure 682 .

[0172] In this embodiment, the first water retaining rib 7311 can guide the condensed water on the first side wall 731 into the first heat exchange drainage structure 671 and the second fresh air drainage structure 682, thereby dispersing the condensed water condensed on the fresh air cover 7, reducing the amount of water in the fresh air drainage structure, and reducing the situation where the fresh air condensed water is sucked into the suction force of the fresh air operation.

[0173] The first water retaining rib 7311 is provided at the bottom of the first side wall 731 along the height direction to reduce the condensed water on the first side wall 731 from flowing into the first volute tongue air duct V2 along the direction of gravity.
